I-15 Tech Corridor


Ames Construction performed the award-winning I-15 Lehi Main to S.R. 92 Technology Corridor project, widening I-15 in Lehi, Utah, from four to six lanes in each direction. The project included new concrete pavement and the construction of underpass bridges and frontage roads. Crews also smoothed out concrete and bridge transitions and connected new trails into a regional system.

Ames’ work scope included two full interchange redesigns, a one-way frontage road system between the two interchanges, 15 bridge replacements, a new bridge over I-15, a new flyover ramp, and bike and pedestrian trails.

The project’s Triumph Boulevard overpass was so important for better east-west connectivity that extraordinary efforts were made to complete its construction within the project’s first six months. Crews were challenged to relocate many complex utilities into the same limited space, including overhead power, water, sewer, gas, and multiple telecom fiber optic lines. Adding to this challenge, existing utilities were also in conflict with major features of the new bridge and roadway.
